LNK2W682MSEH

The LNK2W682MSEH is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNK series. It provides 6.8 mF (6800 µF) capacitance at a 450 V rating in a radial can with screw terminals, intended for general-purpose applications that require high-voltage capacitance with elevated ripple-handling capability.

Key value propositions include high rated ripple current at both low and high frequencies, a 5000-hour load life at 85°C, RoHS compliance, and a robust screw-terminal package for secure, high-current connections.

Key Features

• Electrical performance — 6.8 mF (6800 µF) capacitance with a 450 V rated voltage and ±20% capacitance tolerance (–20% to +20%).
• High ripple-current capability — Rated ripple current of 20.7 A at 120 Hz and 28.98 A at 10 kHz for effective ripple handling across low and high frequencies.
• Long endurance — Load life of 5000 hours when subjected to rated ripple current and DC bias at 85°C, with defined post-test limits on capacitance and impedance.
• Screw-terminal mounting — Radial can with screw terminals provides reliable mechanical connection and simplifies installation for high-current applications.
• Operating temperature range — Specified for –25°C to +85°C to match a range of ambient operating conditions.
• Leakage and safety characteristics — Leakage current specified at 5000 µA; insulation resistance and voltage proof characteristics are specified in the LNK series documentation.
• Physical and packaging — Large-form factor: diameter φ76.2 mm × length 155 mm; supplied in cardboard packing and available for mass production.
• Compliance — RoHS compliant.

Typical Applications

• Power conversion and filtering — Use where 6.8 mF at 450 V is needed for DC-link filtering or bulk energy storage, with high ripple current capability for both low- and high-frequency conditions.
• Industrial power systems — Suitable for general-purpose industrial equipment requiring robust, high-voltage capacitors with screw-terminal connections for secure mounting.
• High-ripple environments — Appropriate for circuits exposed to significant AC ripple given the specified 20.7 A (120 Hz) and 28.98 A (10 kHz) ripple ratings.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage circuit stages that require substantial capacitance.
• Dual-frequency ripple handling: Explicit ripple-current ratings at 120 Hz and 10 kHz provide quantifiable performance for both mains-frequency and higher-frequency applications.
• Durability under load: 5000-hour endurance at 85°C under rated ripple and DC bias gives predictable life performance for design planning.
• Secure screw-terminal interface: Screw terminals facilitate reliable, high-current connections and straightforward installation in equipment assemblies.
• Large capacitance in a screw-can package: 6.8 mF in a φ76.2 × 155 mm can provides substantial bulk capacitance where space and robust mounting permit.
• Regulatory compliance: RoHS compliance supports use in regulated product lines.
